COLUMBIA UNITED STATES PATENT orrron JOHN W. PERKINS, OF PORT NORFOLK,VIRGINIA.

RAILWAY-CROSSING.

To all whom it may concern:

Be it known that I, JOHN W. PERKINS, a citizen of the United States ofAmerica, and resident of Port Norfolk, in the county of Norfolk andState of Virginia, have invented certain new and useful Improvements inRailway-Crossings, of which the following is a specification.

This invention relates to certain new and useful improvements in railwaycrossings and pertains more particularly to a continuous railwaycrossing and while designed more particularly for street railways, itwill be evident as the description proceeds that it is in no wiseconfined to street railway traflic.

The present invention has for its object among others to provide asimple and improved form of continuous railway crossing composed of fewparts, those readily assembled and reliable and efiicient in use and notliable to get out ofrepair. I so construct and arrange the parts that nofrogs are necessary and the line is normally closed, the movable membersat the angles of the crossing being arranged to overlap and normallyclosed, the construction and arrangement of parts being such as to avoidor prevent pounding as the wheels of the train pass over the points ofintersection of the rails, the result being that all noise generallyincident to crossings is practically eliminated.

I aim further at the accomplishment of such other ends as are usuallysought in this class of devices.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be particularly pointed out in theappended claims.

Vhile the structural embodiment of the invention as herein disclosed iswhat I at the present time consider preferable, it is evident that thesame is subject to changes, variations and modifications in detail,proportion of parts etc, and I, therefore, do not intend to restrictmyself to the exact construction herein disclosed, but reserve the rightto make such changes, variations and modifications as come properlywithin the scope of the protection prayed.

The invention is capable of embodiment in a variety of forms, thepreferable ones of which only I have chosen to herein illustrate.

The invention in its prefererd form is Specification of Letters Patent.

1. Fig. 5 is a similar section on the line 5-5 of Fig. 1. Fig. 6 is avertical cross section on the line 66 of Fig. 1. Fig. 7 is a perspectiveview of one of the movable Fig. 8 is a perspective view of Fig. 9 is avertical cross section similar to Fig. 5, showing a slight modification.

Like numerals of reference indicate like parts throughout the differentviews.

Referring to the drawings, 1 designates what may be termed the main linetrack WVlJlCll, 1n the present instance, is shown as open, that 15 withthe parts in posltion when a train is passing over the same in thedirection of the arrow in Fig. 1.

2 is the track at right angles thereto and which, in Fig. 1, is shownwith the movable members closed, it being understood that normally, thatis when a train is passing, the movable members of the main line trackwill also be closed.

At the outer corner of each angle of the crossing I provide the angularmember 3 and between said members the rail portions 4; are disposed.These rail sections midway between the angles are given the form of theusual rail, as seen best at- 5 in Fig. 6, and indicated by dotted linesin Fig. 1. These sections 4 each has connected therewith a clean-out boX6 with a cover plate 7 of any preferred construction and each of themembers 4 is provided with a horizontal lug 8, as seen best in Fig. 5,having an opening 9 in which is received the stud or member 10 dependingfrom the movable member 11, a nut 12 usually being employed, as seen inFig. 5 upon the lower end of said member 10 for an obvious purpose. Thismember 11 has movement in the recess 13, the opposite walls 14 and 15 ofwhich serve to limit the movement of the said member 11, as will beevident upon reference to Fig. 5. The wall 15 tapers, as seen in Fig. 1,being thicker, as seen at 15 as it approaches as seen in Fig. 1.

the angle of the crossing, the member 11 tapering correspondingly. InFig. 9 I have shown a spring 16 around the pivot or pintle 1O confinedbetween the nut 12 on said pin and the under side of the lateralextension or projection 8 which, in this instance, is thinner than thecorresponding portion 8 in Fig. 5, so as to provide room for the springto allow of the necessary vertical movement of the pin and the member11, as will be readily understood. These boxes 6 serve as clean-outboxes, access being had thereto by removal of the cover plates 7, aswill be readily understood.

Each member 1 is provided with a recess 17,-as seen best in Fig. 1, forthe reception of the lug 18 on the member 11, the square face orshoulder 19 thereof engaging the corresponding walls of said recess, aswill be evident from an inspection of Fig. 1. The member 11 is providedwith a depres sion or cutaway portion 20, as seen best in Fig. 7, toallow of the passage of the flange of the wheel. The member 22 isprovided with a pin or pintle 23 received in an open ing in theright-angled portion of the adjacent member e, as seen in Fig. 1. Thismember 22 has the lateral lug 24 received in the adjacent recess 17 ofthe adjoining member, as seen in Fig. 1, and is provided with thedepression or channel 25, as seen in Fig. 8, in which the reduced endportion 21 of the member 11 is received and adapted to slide, it beingunderstood, as will be seen in Fig, 1, that the free end portions of themembers 11 and 22 cross each other, these parts being arranged one abovethe other, so as to allow freedom of movement of each. The free ends ofthe members 11 and 22 are curved inwardly, as seen in Fig. 1, for anobvious purpose.

Within the inner angles of the crossing are the boxes 26 having coverplates 27 and within each box 26 is secured an angular member 28 in anysuitable manner. 29 are pins working loosely through the angular wallsof this angular member, springs 30 being arranged around each pin, asseen in Fig. 1, and the pins projecting through the adjacent walls ofthe box, the extended end of each pin being in contact with the adjacentfree end of one of the members 11 or 22,

Suitable nuts 31 are provided for adjustment of the springs as oocasionmay require. Normally these springs tend to force the free ends of themembers 11 and 22 outward, so that the lines are closed, but when apassing train comes to the crossing, the flange of the wheel entersbetween the member 3 and the adjacent face of the member 11 or 22 andforces the same out or away from the member 3, compressing the spring,and as soon as the train has passed, the springs force the members backinto closed position. The members 11 and 22 are automatically moved toopen position by the passing train and are automatically returned toclosed position by the springs. The parts are few in number, not readilytampered with, require no attention on the part of the engineer or otherperson and are not readily affected by any atmospheric conditions. Partsmay be used without the whole and some parts may serve effectually inconnection with other parts of a form different from that hereindisclosed.

I Vhat is claimed as new is 1. In a continuous railway crossing, angularrail members at the angles of the crossing, intermediate rail members,pivoted members extended at right angles to each other and overlapped atthe inner angles of the crossing, and means disposed at right angles toeach other and independently acting on the free ends of said pivotedmembers to normally hold them in closed position.
